Abstract

Une boucle à phase asservie à large bande, un système de correction d'erreur de synchronisation de boucle à phase asservie à large bande, un procédé de correction d'erreur de synchronisation et un procédé de réglage d'un appareil de radiocommunication doté de la boucle à phase asservie large bande possédant une précision de modulation améliorée. Une partie boucle à phase asservie comprenant un oscillateur commandé en tension (101), un diviseur de fréquence (105), un comparateur de phase (104) et un filtre à boucle (103) sont également prévus. A la fois le rapport de division de fréquence du diviseur de fréquence (105) et la tension d'entrée de l'oscillateur commandé en tension (101) sont commandés, en fonction des données de modulation de phase (121), pour ajouter la modulation. Un inverseur (113) est utilisé pour inverser, soit la phase des données de modulation de phase pour moduler le rapport de division de fréquence, soit celle des données de modulation de phase pour moduler la tension d'entrée de l'oscillateur commandé en tension (101). Un circuit de commande de retard (110) détermine une erreur de synchronisation basée sur un signal (133) obtenu par l'addition des signaux de sortie (131, 132) d'un filtre (106) et d'un filtre à boucle (103), et utilise des circuits à retard (111, 112) pour moduler la synchronisation, et corriger ainsi l'erreur de synchronisation.
